A doctor accused of sexually assaulting a male patient on a busy hospital ward said he has never been attracted to men.

The locum doctor was working at the Norfolk and Norwich University Hospital when the incident is alleged to have happened in September last year.

The victim, who cannot be named for legal reasons, said the doctor groped and then performed oral sex on him while inserting a catheter.

The attack is said to have taken place behind a curtain while five other patients lay nearby.

The court has heard from two men who claim they were assaulted in the same way by Arora at the University Hospital of North Tees in Stockton-on-Tees, Cleveland, four years earlier.

Indian-born Arora received a caution from West Midlands Police after being caught engaged in a sex act with another man in Sandwell Valley Park near West Bromwich less than two weeks after the alleged incident in Norwich, the court heard.

The married father-of-one told the court this was his first homosexual encounter.

He said: "I have never been interested in men. I had never engaged in sexual activity with a man at all."

Asked by prosecutor Andrew Shaw why he was caught at the well-known "cottaging" spot near West Bromwich, he added: "I was under a lot of stress.

"I didn't know that those things happened there.

"I was walking and a man asked me how I was and told me to come with him."

He accepted that his nationality and Hindu faith meant a stigma was often attached to homosexuality.

Earlier in the trial, the patient who says he was attacked at the Norfolk and Norwich hospital described how Arora complimented him on the size of his penis before groping him.

He saw his head moving up and down and the doctor touching himself.

He said: "I didn't think at first it was that, you go to hospital for help not for somebody to take advantage of you."

Arora said that he had stayed with the patient after a nurse left them alone to "clean up".

He has said that any contact with the victim's penis was medically necessary.

The doctor said this would have taken a matter of seconds, not the seven minutes he is alleged to have stayed.

Jurors are expected to retire to consider their verdict later today or early tomorrow.
